OBJECTIVES/HYPOTHESIS To establish the effect of self-directed virtual reality (VR) simulation training on cadaveric dissection training performance in mastoidectomy and the transferability of skills acquired in VR simulation training to the cadaveric dissection training setting. STUDY DESIGN Prospective study. METHODS Two cohorts of 20 novice otorhinolaryngology residents received either s...

We study the formation of primordial proto-stars in a ACDM universe using high-resolution cosmological simulations. Our approach includes all the relevant atomic and molecular physics necessary to follow the thermal evolution of a prestellar gas cloud to very high densities. We describe the numerical implementation of the physics. We show the results of a simulation of the formation of primordi...
